While I have shown and described my means in combination with the elements'o'i an undenfeed stoker, it is to'be understood that such agitating means is not solely restricted to fthe use in such combination, as the same may be, employed successfully in connection ,with the elements of various furnaces andstokers.

In the accompanying numerals are employed to designate like parts throughout the same, Figure 1 is a side elevationof an under-feed stoker, showing my apparatus applied thereto, a plan view ofthe same. Fig. 3 is a central vertical longitudinal sectionalview through the same, partsbeing shown in elevation, and. Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 3. t

Inthe drawings, wherein for the purpose of illustration is shown a preferred er n-' bodiment of my invention, the numeral 5 designates a magazine, retort or trough of an under-feed stoker. which is arranged between and beneath the grate-sections of furnace. as is well known in the art. This Fig- 2 is Specification of Letters Patent.

The numeral 10 designates twyers, ar ranged upon the flanges 7 and carrying depending lugs 11, entering the pockets 8, as rnore clearly shown in Fig. 4.

. Arranged Within the upper portion of the magazine 5 between its endsare vertically vswinging agitator elements or bars 12, pivoted between their ends with the side walls of the magazine, by means of bolts 13 or the like. Pivotally connected preferably with the rear ends of the agitator elements or bars 12 is a preferably U-shaped connecting link 14: including two arms 1.4 which are pivotally connected with an agitator block 15, as shown. This agitator block is rigidly mounted upon a reciprocatory rod 16 which has its rear endoperating in a guide sleeve 17, as shown. Any other suitable means may be employed to pivotally connect the substantially U-shap'ed link 14 with the rod-16.-

Bolted or otherwise rigidly attached to the forward-end of the magazine 5 is a. fuel feed'casing or cylinder 18, having a feed hopper 1.9, bolted thereto, as shown. The upper portion of the feed casing is provided with an opening 20, normally covered by a plate 21, held in place by bolts 22.

Disposed to reciprocate within the feed cylinder 18 is a feed plunger 23, which is preferably h llow and adapted to force the fuel from the feed cylinder 18 into the g Extending longitudinally within the hollow feed plunger 23 is a connecting rod 24, rigidly connected with the rear end thereof and'provided at its for ard end with a depending exjtension or crank 25,:operating through an elongated slot .26 formed in the lower portion of the feed casing 18. The extension 25 is pivotally connected with the rod 16 by a bolt 27 or the like. h

The numeral 28 designates a steam engine cylinder'which is bolted orotherwise Patented Mar. 28, 1916.

, fuel; are very agitating the fuel. .v a It isto beunderstood that the form of my invention herewith shown and described is I to be taken as a preferred example. of the pressure into the opposite ends of the cylinder )8, to cited a reciprocation of the piston and elements connected therewith to be moved thereby The ,valve' 31 'is operated by a valve steu'ror rod 32, mounted to slide in stationary guides 3 bolted or otherwise rigully secured to the casmglS. Rings or collars 3 are rigidly mounted upon "the stem or rod 32 and are adapted to beengaged by a head shdmg upon thero'd32 and formed integral with an arm 36,11av1ng its lower endriuidly secured to the extension 25 by any suitable means.

The operation of the apparatus is asfo'lljtm sz; As the piston 29 reciprocates in the "cylinder 2S the plunger23 moves with it 'in the feed cylinder 18, whereby the fuel.

passing downwardly from the hopper 19 is fed into the magazine and forced up wardly therefrom upon thegrate orgrate- ;sectio'ns of the furnace; as iscustmnary in The movement of the I .piston 29 through the medium of theasso- ,ciated elements, serves to automatically operate the valve 3 1,ccontrolling the inletand exhaust of the fluid pressure toand from the opposite ends of the eylinder 28 as in theoperation of the ordinary steam enginei pThe movement of the plunger 23 reciproeates-the rod 16, whereby U-shaped link 14 is made to alternatelyiassume forward and rear inclined positions as the substantially illustrated in Fig. 3. I This movement ofthe link causes the agitator velements or bars 12 to-alternately assume rearwardly and for wardly inclined-positions. I have found ythat the agitatorbars 12 and links 14 by vertically swinging in the presence offthe effective in breaking up and same,-and that various changes in the shape,
